RUGGEDCOM Ethernet Switches and RUGGEDCOM Serial Device Server

Certificate

Module description

The RUGGEDCOM Ethernet Switches and RUGGEDCOM Serial Device Server are utility-grade, fully-managed Ethernet devices designed to operate reliably in electrically harsh and climatically demanding environments. The devices’ rugged hardware design, coupled with the embedded Rugged Operating System (ROS®) version 4.2.1.F, provides improved system reliability and advanced cybersecurity and networking features. This makes them ideally suited for creating secure Ethernet networks for mission-critical, real-time control applications.
